Abstract (en)
[origin: US5892082A] The present invention is directed to a process for the preparation of the reagent dimethyl titanocene (Cp2Ti(CH3)2) from titanocene dichloride (Cp2TiCl2) and a methyl magnesium halide, in particular, methyl magnesium chloride (CH3MgCl). The instant process provides the desired reagent in a manner which is generally less hazardous and more economical than previous methods.
